RECIP ROCATING PROPELLER.

SPECIFICATION forming part of Letters Patent No. 274,693, dated March 27, 1883,

Application filed February 21, 1883. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH A. ARTHUIna citizen of the United States, residing in the county of Logan and State of West Virginia,

U will enableothers skilled in the'art to which it appertains to make and use the same.

This invention relates toimprovementsin reciprocating propellers,and in the mechanical movement for operating the same, which has for its object to utilize the weight and muscular power of the operator. This object is attained by the mechanism illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is a plan view. Fig. 2 is a side elevation with some of the parts broken away.

Fig.3 is a modification of my invention. Fig. 4 is a detail view.-

The letter A represents a vessel.

.A. indicates a frame which may support the driving mechanism.

A is a frame extending over the side of the part of the beater boat or vessel, and supports the propellers and their operating devices.

0 is a platform attached to the rock-shaft E.

of its radiating arms the crank D, to which is secured the upper extremity of the pitman E, and the other end is pivoted to the treadle or platform 0. I

H isa pinion which gears into the spurwheel H.

G is the shaft of the pinion H, and is supported in suitable bearings in or attached to the frame B. It is provided with a double crank, G and G, and extends across theframe A and is journaled-thereto by suitable boxes.

J J are pitmen, attached respectively to the cranks G and G and to the sliding frames U U! U U!!! I i b are grooves in the frames B and A in whichthe frames U U U U! are adapted to slide back and forth.

b b are hangers, to which are journaled the reciprocating propellers I. j V

W represents pieces of wood or metal,which extend from the slides U to U and from U to U, and thus connect these parts to each other.

I- are the buckets or propellers, which are swung on journals attached to the upper part, and are provided with arms 0 and O, extending therefrom at an acute angle in an upward direction. 7

B R are lugs attached to the beams W, and form a support for the rock-shafts Q.

P are studs extending upwardly from the shafts Q.

Q are arms, which curve downwardly from the rock-shafts Q.

ff are springs, which bear upon the upper portion of the rock-shafts Q at a part which is out into an angular shape, and are intended to hold these shafts at the proper angle and for purposes hereinafter described.

F and F are cranks connected to each other by a horizontal rod, L, and are located on one side of the frame B, through which extend rock-shafts F F, which are supported by suitable bearings, and have attached to their outward extremities the arms M M, which are provided with short arms m m m m, the

change the motion of the vessel to a backward or forward direction.

eis a small piece projecting from the hanger b, and is intended for a stop to prevent the propellers I from going too far in a horizontal position.

K is an arm projecting from the frame B, the end of which is intended to strike against the arm 0 and change the position of the propeller I.

K is an arm projecting from the frame A, and is for the same purpose as K.

S are slots in the frame B, and S are bolts and nuts, by means of which the frame B may be adjusted to different heights, and then fastened to the vessel in a position to give the propellers a smaller or a greater dip. I

The cranks G and G and pitman-rods J J cause the slides U and U to move in opposite directions, one forward and the other back ward, at the same time. In the forward motionthe propeller assumes a nearly horizontal position, while in the backward motion of the slide the propeller is nearly vertical and drives the boat or vessel in a forward direction. To change this it is only necessary to turn the crank F, when the arms M and M will assume inclined positions to the right or left, and cause the short arms at m m m to engage with the studs P P and change the directions of the curved arms Q in such a manner as to strike against the arms 0 O and alter the previous position of the propellers. One portion of the rock-shafts Q is of an A shape, as shown in dotted lines in Fig. 4. The springsfbear upon this part, and by this means hold the rock-' shafts Q in any position in which they may be placed by the action of they short arms at m m m.

In Fig. 2 the oscillating platform 0 is shown in dotted lines, and in Fig. 3 in full lines. The platform 0 is intended as a standing-place for the'operator, who is to place one foot at each end on the curved portion of the platform at the same time that he grasps with his hands the crank-handle D, and as he throws his weight alternately on one foot and then on the other and turns the crank D with his hands, a rotary motion is given to the wheels H and H, and the slides U U U. U are caused to reciprocate by the action of the cranks G and G and their pitman'rods J and J, together with the propellers 1.

Having described my invention, what I desire to secure by Letters Patentand to claim '1. In a reciprocating propeller, the combination of cranks F F and connecting-rod L with rock-shaft F and armsM M, said arms serving to support the feathering mechanism of a reci rocating propeller, substantially as described, and for the purposes set forth.

2. In a reciprocating propeller, the combination of shaft G, cranks G G on said shaft, connecting pitman-rods J J, with slides U U U U, which carry the paddles, and have lugs R, adapted to hold the rock-shafts Q in the specified relation to the paddles, substantially as shown and described, and for the purposes setforth.

3. In a reciprocating propeller, the combination of the propellers I, having arms 0 O, with the rock-shafts Q, having studs P and curved arms Q, with which the arms 0 0 engage, substantially as described, and for the purposes set forth.

4. The frame B, carrying the reciprocating propeller and the operative mechanisms, substantially as described, and having slots S,

combined with retaining-bolts or similar devices operating in said slots, whereby the frames and propellers may be raised or lowered, as stated.

5. The oscillating platform and the hand wheel H, connected together by a pitman, and operating the propeller by means of connecting mechanism, substantially as described,
